Last names as first names

I know there are tons of last names used as first names for boys but I have not found any that have a french origin, most I find are Irish.

Can you list some (please only French)?

You could do an internet search of the most common surnames in [name]France[/name]. I think Wikipedia even has an article that list the most common surnames of every country.

I usually like the behindthename lists but since someone else already suggested those how about this one? French Surname Meanings and Origins

Looking through it I was surprised how many of them seemed so un-French and like normal FNs.
